I've read the books and I've seen the show, and I think the books are great (well the original trilogy, less so the sequels and prequels) and I'm very much enjoying the show. I'll be bereft after the season finishes, so long to wait!
Reading the comments it's interesting that someone can write a long post explaining in some detail why they like the show, and get a majorly 'unhelpful' rating, while someone can write something to the effect of 'this show sucks' and somehow this pithy response is rated very helpful indeed.
Clearly there are a lot of people on here with axes to grind. I'd say to anyone looking in who hasn't seen the show yet - don't let 'em grind their axes on you, watch the show and make your own mind up.
It's not perfect, some of the dialogue is a bit clunky, some of the action scenes are a bit rushed and maybe overcomplicated, and there are a few points where you think, well that wouldn't happen. Grist for a nitpicker's guide mill perhaps, but there's a sweep, an overarching story, and some great imagination at work to realise this. And Asimov's story is always there behind everything.
At least give it a chance. This is series one. I'd say as season ones go, this is a pretty good one.
